Review of RAB-based irrigation prices 2027–29

On 30 October 2025, the Queensland Government directed us to investigate and report on appropriate prices for the irrigation services provided by Sunwater and Seqwater, derived using the regulatory asset base (RAB) approach. These prices are to be based on allowable costs that are consistent with our positions from the review of irrigation prices for 2025–26 to 2028–29, adjusted to reflect the use of the RAB approach for recovering renewals expenditure.

Following consultation with stakeholders in March 2026 and the receipt of stakeholder submissions in mid-April 2026, we published our draft reports on 3 July 2026. We have also published scheme information sheets that provide an overview of our draft findings for each scheme.

We will be holding workshops (in-person and online) from mid-July. The workshop schedule is available below. If you would like to attend a workshop, please call the QCA on (07) 3222 0555.

We invite stakeholders to make submissions on the draft reports by 7 August 2026. For further information or to make a submission, visit our submission page.
